St. Patrick did such a good job banishing snakes from Ireland that he removed all evidence of there having been there. To date not a single snake fossil has ever been found on the Emerald Isle.
But, 300 million years ago, some superficially snaky amphibians slithered through the primordial Irish coal swamps. These were the Aïstopods. And you will recall that I wrote a terrible limerick about them some years back. Or maybe you don’t recall that, but now you do.
